Last year's moonshot splashed up lots of waterLOS ANGELES – When NASA blasted a hole in the moon last year in search of water, scientists figured there would be a splash. They just didn't know how big. Now new results from the Hollywood-esque moonshot reveal lots of water in a crater where the sun never shines — 41 gallons of ice and vapor.

That may not sound like much — it's what a typical washing machine uses for a load — but it's almost twice as much as researchers had initially measured and more than they ever expected to find.

The estimate represents only what scientists can see from the debris plume that was kicked up from the high-speed crash near the south pole by a NASA spacecraft on Oct. 9, 2009.

Mission chief scientist Anthony Colaprete of the NASA Ames Research Center calculates there could be 1 billion gallons of water in the crater that was hit — enough to fill 1,500 Olympic-sized swimming pools.

"Where we impacted was quite wet," Colaprete said, adding there could be more such craters at both the moon's poles...
